G’day Frank,
Thanks for answering my question, twice … 
The impact a little underscore can have. Great find mate! It actually explains why quite a few calls on my end didn’t work. All fixed now!
If you install MobiFlight you can opt-in for betas in the settings and then update the app to 8.0.2.1. But yes, your method works well especially to keep the amount of external programs manageable.
I’ll have to check out their discord - many thanks. I found their forum but it’s quite bare for MSFS.
Yeah me too, I like the simplicity of using Python to control the X-Touch-Mini.
Thanks again mate,
Michiel
